CTF Name: Position
Topic: Cryptography
Flag Format: IHC_CTF{}
CTF Link: https://t.me/ctf_invisiblehc/95
Description:
Download the text file and decrypt the text
Solution:
After opening the ciphertext file, we discovered a cipher text. Upon analyzing the cipher, we realized it was encoded using the Letters Positions cipher.
We decoded it using this online tool:
https://www.dcode.fr/letter-positions
The decoded message revealed the partial flag: "IHC_CTF{LR_PN_CRYP}"
However, since the Letters Positions cipher doesn't provide integers in the output, we manually inferred and completed the flag.
flag: IHC_CTF{L3773R_P051710N_CRYP70}
